Application filed March as,

with internal combustion engines, and-the 1 object of this improvement is to provide a siinple and'eiiective means whereby an acceleration of speed will be produced in the magneto in order to produce a hot spark for starting the internal combustion engine.

Other objects will appear hereinafter. Our invention consists in the combination and arangements of parts hereinafter described and claimed. The invention will be best understood hy reference to the accompanying drawing forming a part of this specification, and in which,"

Figure 1' is an elevation of a connection omhod y taken on mg our invention, 'Fig; 2 is a section line 2-2 in Fig. 1,-and Fig. 31s a.

view si'uiilarto Fig. 1, but showing certain portions in different positions.

The preferred form -.of construction 'as illustrated in the accompanying drawing comprises -a .driving connected in any suitable manner to the crank shaft of an internal combustion enlginc, not shown. A hub 5 is provided with an extension (5 which provides a journal for the gear 4. V The hub 5. is rigidly fixed on car 4 adapted to be shaft 7hy means of a nut 8 pressing said hub against'a Washer 9 and the latter against a shoulder 10 on shaft 7. Theshaft-Y'represents the brokcnotl' end of a magnetoarma turev shaft, the construction being such that gleig t is permitted to rotate on journal 6 of .;recess 12, the 'latter'being a drill-hole in the bottom of recess 11. A corresponding drillhole 13 is formedin .gear 4 and a-.helical' spring- 14' is positioned in recess'll with its ends inserted in constructionestablishes a resilient connection between driving gear lan'd hub 5, as" will be read ly understood.- In the outer The hub is provided with an an nular recess 11 and'in the recess .11 is another I drill-holes 12 and 13-. This.

I engaged against pin 15 and resilientl main- RUnoLr and tainedtherea ains't by the tension 0 spring,

1 1, the latter eing placed in recess 11 under a slight tension, the tension of spring M'being. sufficiently strong to cause gear t to drive hub 5 without disengaging pins 15 and 16. Also in the periphery of hub 5 is positioned a pin 17, the latter'bein' provided with an inclined outer face an forms a stop by means of which rotation of hub 5 is temporarily lockedby means of a catch'18. The, catch 18 is pivotedas at 19 'to a fixed meme ber 20; the member 20 may, be a portion of the magneto frame or any. other suitable article. The catch 18 is iiiade of a length and disposed in a manner so that it maybe rocked to inoperative condition by means' ol' a weighted arm 21, the. latter being pivoted at pivotalpoin't 19 of catch 18, the Weighted arm 21 being formed in amanner that when in the position indicated in Fig. 1, a shoulder'22 vformed"thereon rests on the cap 18' in a manner to maintain the lattergin inoperative condition, and when the Weighted arm 2-1 is manually moved to the position $13 indicated in Fig ;3, shonlder 22 rests on a portion of catch 18' ontlie opposite side; of

Upon unlocking stop 17, the tension of spring 14 causes the hub to be rotated at a high rate of speed until pin 16 again engages pin or catches up with gear 4. Thls highly increased rate of speed of hub 5 and conse quently shaft 7 causes the armature of the magneto to be rotated very fast, and produces. a hot spark for igniting the first charges of fuel introduced into the engine to effect starting thereof. While we have illustrated and described the preferredforin of construction for carrying our invention into effect, this is capable of variation and modification without dearting from the spirit of the invention.

.' Ve, therefore, do not wish to be limited to the precise details of construction set forth, but des1re.to avail ourselves of such varlat1ons and modifications as come within the scope of the appended claims.

Having described our invention what we claim as new and desire to secure by Letters Patent is:

1. A device of the kind described compris ing a driving element; a driven element mounted adjacent said driving element; a

springoperatively connecting said driving .and driven elements; a stop on said driven element; a catch movably mounted and adapted to be moved into the path of said stop; a weight shiftably mounted on said catch and adapted to be manually shifted to maintain the-latter in the path of said stop; and a. cam carried by said driving elementadapted to disengage said catch from said stop and shift said wei ht to 'maintain said-catch out of the path of said stop, substantially as described.

2, A. device of the hind described comprising a, t'lifivingxelement; a driven clement mounted adjacent said driving element; a spring operatively connecting said driving and driven elements; a stop on said driven element; a catch pivotally mounted and adapted to be moved-into the path of said stop; a weight shiftably mounted on said catch and adapted to be manually shifted to maintain the latter in the path of said stop; and a cam carried by said driving element adapted to rock said catch from engagement with said stop and shift said weight to maintain said catch out of the path of said stop, substantially as described.

3. A device of the kind described comprising a driving gear; a hub mounted adjacent said gear; a spring operatively connecting said gear with said hub; a stop on said hub; a catch pivotally mounted and adapted to be rocked into the path of said stop; a

,weight shiftably mounted on said catch and adapted to be manually shifted to maintain the latter in the path of said stop; and a cam carried by said gear adapted to disengage said catch from said stop and shift said weight to maintain said catch out of the path of said stop, substantially as described.

4. A device of the kind described con1prising a driving gear; a hub mounted adj accnt said gear; a spring operatively connecting said gear with said hub; a catch pivotally mounted and adapted to be rocked into the path of said stop; a weight pivotally mounted on said catch and adapted to be manually moved to a position in which said catch will be maintained in the path of said stop; and a cam carried by said gear adapted to disengage said catch from said stop and rock said weight to a position in which the same will maintain said catch out of the path of said stop, substantially as described.
